R(x) (polynomials in one variable)

R(x), when referring to polynomials in one variable, is a mathematical expression made up of terms involving powers of a single variable x, combined using addition, subtraction, and multiplication. These polynomials can be written as a sum like aₙxⁿ + aₙ₋₁xⁿ⁻¹ + ... + a₁x + a₀, where the a's are coefficients. They can describe curves, lines, or other shapes when graphed, and are fundamental in various areas of mathematics, science, and engineering for modeling and analysis.
